To a/ZZ whom it may concern:

Be it known that I, WALTER THOMAS SYKEs, a citizen of the United States,residing at the city of Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented certain new and useful Improvementsin Ring-Doffers forv Carding-Machines, of Which the following is aspecification.

My invention has relation to carding engines or machines; and it relatesmore particularly to the construction and arrangement of thedoffer-rolls thereof.

I-Ieretofore doffer-rolls have beenprovided with detachable rings formedof leather or like material provided With Wires disposed at an angle tothe surface thereof and the rings mounted on the roll at suitabledistances apart. These rings have been formed by inserting Wire staplesinto the leather or like material from the back and so as to project atan angle from the face thereof, but the main objections to such leatherrings provided with projecting Wire clothing have been that theyrequired constant stripping for removal of accumulating extraneousmatter around or about the same,which not only tended to disorganize thenormal or operative positions of the wires for effective action, butalso rendered it necessary to remove the doffer-rolls from the machineand to replace the same with other leather rings provided with Wireclothing. Moreovensuch rings only imperfectly straightened or combed outthe fleece or brousrgematerial in its passage from the cylinder fortreatment by the doffer-rolls preparatory to'further treatment byrub-rolls and its delivery from the condenser or iinisher card forspinning. Again such bands provided with Wire clothing and fastened ortacked to thel surface of the roll of Wood or similar material have beenfound to present further objections, that of the constant tend- -encyaside from clogging .of the spaces tively inexpensive and efficientdoffer-roll or cylinder, comprising a series of detachable metallicrings applied thereto and each provided With spiral grooves into whichare inserted strips or fillets of metal having saw teeth arrangedalongone edge thereof and the strips or fillets inserted and secured in theseries of'spiral grooves of each of the rings With the exposedsaw-toothed edge of 6o each arranged so that the teeth of each of thestrips or fillets of the series occupy a staggered position with respecttothe others and each of the rings detachably applied to the roll orcylinder provided with means for securing the same to positionthereon,in order that the character of Work in the use of suchdoffer-rolls or cylinders in a carding engine or machine may beappreciably enhanced and superior fleece or fibrous material thereby 7oobtained for spinning; second, to provide a doffer-roll or cylinder,comprising a series of saw-toothed metal rings detachably secured toposition on the roll -or cylinder and. consisting of bands or fillets ofmetal inserted into spiral grooves of each of the rings and therespective teeth of each of the fillets or bands of metal comprising therings occupying staggered positions with respect to each other andcalked to position in 8o the spiral grooves of the rings detachablyapplied tothe roll; or cylinder; third, to provide a doffer-roll or'cylinder withdetachable sawtoothed. rings and with means for clampingthe same to position on the roll or cylinder at suitable distances apartalong the periphery thereof, the construction and arrangement being suchas that the fibrous material treated thereby is effectually anduniformly straightened or combed out preparatory to the deliv- 9o ery ofthe same to rub-rolls or aprons for further treatment; fourth, toprovide a dofferroll or cylinder for a condenser or finisher cardingengine or machine having a series of detachable saw-toothed metal ringsmounted thereon and each composed of a series of staggered exposedsaw-toothed metal strips or fillets closely arranged and secured in thegrooves of said rings and the rings provided 1 with means for readilydetaching the same roo A from the cylinder; the construction andarrangement being such as to permit material issuing from the cardingcylinder' to be taken up by the staggered teeth of said rings andthoroughly combed or straightened out in threads or courses and withextraneous matter that may be contained therein removed anterior to thedelivery of the fibrous material as sliverto rub-rolls or aprons fortrans-.

forming or converting the same into roving preparatory to the spinningthereof.

My invention consists of a doffer-roll or cylinder provided withstaggered saw-toothed metal rings arranged at suitable distances apartthereon, and means for clamping the rims of said rings to the roll orcylinder.

My invention further consists of a dofierroll or cylinder for a cardingengine or machine, comprising a series of saw toothed metal ringsarranged 4at suitable distances apart along the periphery of the roll orcylinder and each ot the rings provided with means for detachablysupporting the same to position on the roll or cylinder.

i My invention further consists of a dotierroll for a carding machine,comprising a cylinder, means for heating the same, detachable sawtoothed metal rings arranged at suitable distances apart onthepcylinder, and lneans for clamping the rings to position thereon.

My invention further consists of a doerroll provided at suitabledistances apart with detachable rings having saw-toothed metal strips orfillets set into spiral grooves formed in the rings and the respectiveteeth of each of the rings arranged so as to occupy staggered positionswith respect to each other, and means for clamping the rings to positionon said roll or cylinder.

My invention further consists ot' a doft'erroll for a condenser orfinisher carding engine or machine provided with a series of detachablesaw toothed metal rings and means for clamping the same to position onthe roll; and my invention further consists of the improvements indoier-rolls hereinafter described and claimed.

The nature and characteristic features of my invention will be morefully understood from the following description taken in counection withthe accompanying drawings, forming part hereof, and in which- Figure l,is a perspective view of a saw toothed metal ring embodying the featuresof my invention and having formed integral therewith a recessed taperingand slotted rim or band adapted for the reception of a wire ring forfirmly clamping the saw toothed metal ring to position on a cylinder orroll. Fig. 2, is a front elevational view of the same, showing theclamping device Secured to position'thereon. Fig. 3, is a perspectiveview of a Asection of the ring on the line 3-3, of Fig. l, showing oneof. the slots in the rim or band formed integral with the toothed metaldoffer-ring. Fig. 4, is afrontelevatioualview of the toothed metaldoffer ring, showing the recessed integral rim or band of the sameprovided with openings for runninglsolder or similar material into thesame for firmly securing the rim or band to position in contact with thecylinder or roll. Fig. 5, is a view partly in section and partly inelevation of a section of the cylinder with a section of the ring shownin application thereto and showing solder or similar material insertedin the apertures disposed at suitable distances apart along the rim orband thereof for holding the ring to position in contact with thecylinder. Fig. 6, is a perspective view,showing so much of a condenseror finisher carding machine rub-roll or apron mechanism as will serve toillustrate the application of my improved doffer-rolls thereto. Fig. 7,is an elevational view partly in broken section of the roll or cylindershowing two of such rings as embody the features of my invention inapplication thereto with the clamping means in engagement withtheintegral recessed or slotted rims or bands thereof, illustrating`thereby one means of clamping the rings to position on the roll orcylinder. Fig. 8, isa transverse section on the line 9-9, of Fig. 8,showing a toothed strip or fillet of metal mounted in one of the groovesof the dofer-ring detachably secured to the cylinder; and Fig. 9, is aperspective View of a doffer-roll, comprising a hollow cylinder with asteam or heating coil mounted therein and provided with detachable metalsaw-toothed rings arranged at suitable distances apart along theperiphery thereof, for enabling moist. or damp fibrous material to beworked thereby in order to enhance the quality or character of theresultant fibrous product.

Referring to the drawings a, is a metal ring provided with grooves b,arranged in parallel courses and into which grooves are inserted themetal strips or fillets c, having saw teeth arranged along one edgethereof and in their engagement with the grooves of the rings soarranged as to occupy staggered positions with respect to each other.The ring a, in Figs.` l, 2 and 3, is;l provided with an integralrecessed and tapering rim or band c', provided with transverse T orother shaped slots d, atsuitable distances apart around the peripheryand extending through the body thereof.

e, is a band ot Wire or similar material for insertion into the rim orband c', and serving as one means for clamping the saw toothed rings toposition on the cylinder g. The saw toothed metal strips or fillets c,inserted into the grooves b, of each ring a, are suitably calked orotherwise secured to position so as to become an integral part ot' thering, and in such manner as to etect a thorough .combing orstraightening out of fleece or fibrous material in the rotation ot' eachring mounted on the roll or cylinder g.

In Fig. 4, the recessed rim or band formed integral with the saw-toothedring a, is provided with openings f, for the reception of Solderorsimilar material f2, as shown in Fig.

IIO

5, for maintaining the' said ring 4firmly to position on the roll' orcylinder g; Theupper portion of'the T-shaped "slots formed in theband ofthe saw-'toothed rings a, as shown in Figs. 1, 2 and 3, is slightlytapered from each end 'to'the' middle thereof, in order to 'enhanceitsclamping effect in connection with thecylinder upon the application ofthe Wire e, tothe surface of the rim or band, by reason of the fact thatas the Wire i's drawn closer to the inner` edge of the same, theI metalat the points as and a4, of thebaud, is brought more intimately intolcontact-with thel surface'of `lower dofferrolls employed in'suc'h a ma-`chine. VVh and h', are rub-aprons in broken sectionadapted to formfibrous material into sliver, threads or skeins after passage around andtreatment by the' upper and lower doffer f rolls as illustrated in lFig.6.

`In Fig.'9 is`illustrated a hollow-cylinder provided With end journalsi, having collars fi', mounted thereon'and abutting against the ends orheads g', at the respective ends' of the cylinder g.' j, is -a pipeextending through the journals t', andfforr'ned into coils jz, in theinterior of the cylinder g, for the passage there'- through of Ysteam orother heating medium', in order to Warm the surface of the cylindercarrying "the series of detachable metal sawtoothed doffer-rings. Theend of the coiled pipe jvis connected with the pipej, of the journal fi,by means'of a two-part coupling device js, or iu any otherl preferredInanner and the extremity of the pipe i, is coupled to a heat supply,not shown, but which Will'be readily understood, whereby under dueregulation the surface of the cylinder is maintained in a more or lessheated condition for purposes-to 'bev hereinafter fully explained.

"In some instances the fibrousv material to undergotreatme'nt requiresya mild heat to successfully Work and give as a resultant product bysuchtreatment of Vthe`doffer-rolls, a superior sliver-for subsequent use.AMoreover, the coarse or more coinmon fibrous materials, such as usedinthe making of a`l low considerable Waste even with undue care'exercised,Will accumulate. Practice' has also demonstrated that-such kfibrousmaterials as require treatment in' carding engines ormachines,.areaffected by changes of' temperature, and in such mannera'sto cause the materialto become rampant orlwild, and it is asource"oficonsiderableftrouble at times to' properly manipulate orhandle the same so as to secure uniformity or regularity inthe 'deliveryfrom the carding cylinder-to the doery rolls or cylinders;

In the employment of doffer-rolls such as hitherto employed With leatherbands having staples-inserted therethrough to form teeth .projectingfrom the face thereof, in the introduction'of heat into the interior ofthe cylinder, it has been found in attempts made in that direction, thatsuch deleteriously affects y the leather, that is, causesthesame toWarp, as Well' as destroys the position and efficiency of the staplesforming the clothing thereof. Moreover, the Warping of the leather bandhas superinduced undue clogging of extraneous matter around and aboutthe staples and to overcome Which has beena desideratumfor 'a long timeand adilemma Whichv has been regarded as insurmountable, because meanshave not proven inthe past to be at hand to overcome successfully thesame or accomplish the desired results, until a doffer-roll orcylinderconstructed according tol my invention Wasdesigned,and practice hasfully demonstrated, .that `the 'above' mentioned objectionable' featuresareM entirely overcome, whereby such materials jas hereinbeforedescribedA can be' treated with the employment ofsuch doffer-rolls Vorcylinders under any and allv conditions"Y o1" lchangesof temperaturewith a resultant 'su- 2perior product by such treatment and withtherebya great saving of Waste made.' More'- over, with a saving 'oftime and labor of stopping the machine to strip the doffer-rings'of therolls or cylinders, because such rin-gs are self :strippers in thisrespect, that the'fibrousY Vmaterial by reason'o'f the arrangement-ofthe hereinbefore described, maybe mentioned,

first, that the iieece or fibrous material treated thereby is thoroughlycombed or straightened outand stripped of extraneous matter before beingpresented' to the rub-rolls or apronsfo'r forming the same into sliver;Ysecond, byreason 'of the arrangement ofthe saw-toothed fillets or stripssecurely in the groups of grooves o f the series of rings'detachablyapplied to'the `roll or cylinder g, and With the respectiveteeth thereof occupying-staggered positions Withrespect to each other,are due the' superior'results'obtained ofthe thorough combing ont of thematerial undergoingtreatment thereby and the utterlack of adherence ofextraneous matter thereto, because practice has demonstrated that theydo not become clogged with such matter or with the iieece or fibrousmaterial undergoing treatment, and hence stoppin g of the machine isentirely avoided and the fleece or fibrous material combed orstraightened out into parallel threads or courses thereby, isappreciably enhanced and commands a higher figure as an article; third,greater uniformity in the Working of the material is eifected and a farbetter resultant product by the treatment is obtained; and, fourth,owing to the solid character of the saw-toothed rings there is an entireabsence of any tendency of the same to Warp or to Work loose on therollor cylinder; and moreover, these doffer-rolls or cylinders can beset closerto the cardin g cylinder, thereby insuring more perfectclearance for the stock or other matter delivered therefrom and thus toenable the carding cylinder to present a superior quality or characterof material for the complete or thorough straightening, combing out orcleaning by the doffer rolls and anterior to the presentation of thesame to the rub-rolls or aprons for transforming the fibrous or tieecymaterial into sliver preparatory to the spinning thereof for subse quentuses in the arts.

Having thus described the nature and ob jects of myinvention, what Iclaim as new, and desire to secure by Letters Patent, is
